T all-"whomz't may concern:

-Be-it-knownthat I;- FRANK KRQNEN BIT ER, a citizen of theUHiiZQd'ShQieQBLITQ siding at Maywood; "in the county ofGook and Stateof Illinois, have invented new and useful Improvements in Percolatorspouts, ofwhich the following is a specification.

My inventionrelatcs to improvements in coffee pots, percolators andother articles constructed of aluminum or otherkindred material, havingparticular reference. to im proved means and methods of attaching anoutlet spout to such receptacles A Percolators; cofl'ee pots and fsimilar articles of aluminum are formed while the metal is soft, afterwhichit isspun and burnished torender it hard. The spout or outlet is'then applied, generally by welding, sincesoldering in such instances isnot considered dependable for permanent purposes. It has also heretoforebeen proposed to attach the spouts to such receptacles by means-ofriveting. The difiiculty with the welding process of attachment of thespout is that it softens the vessel at the site of the spout so that itbecomes weakened and will dent or warp when the spout is struck orknocked against an object. :The objection to riveting is that suchprocedure results'in cracks and crevices whidhgather'd'irt; thusrenderingthe vessel unsanitary and slojvenly looking. In: boththewelding and riveting methods of attachment, it is very difficult toform thejoint between the vessel and the spout so that the edges of thespout will be flush with the outer surfacev of the vessel. It-istherefore theprim-aryobjectof my invention-to provide a novel andimproved 'means and method of attaching spouts to vessels of thischaracter which will overcome the objections noted hereinbe-fore andwhereby a strong and durable attach:- ment of the spout to the vesselwill be made in a; highly expeditious man r W h however increasing thecost of the finished product.

A further object of the invention is to provide a novel and improvedjoint formation between the spout and the vessel whereby leakage will beprohibited.

With the above and other objects in view, the invention comprisescertain novel features and methods of construction and arrangement ofthe various parts to be herem ter descri e ted l ed, in a ea that thesame may be better understood, reference is had to theaccompanying-draw.- ings forming a partrof this specification.

Fig. 8 is a perspective view of the spout removed,, and

F g. ,9is asectional detail of the joint be tween the spout and vessel.1

Referring specificallyto drawings,' where in for the purpose ofillustration the preferred embodiment of the invention is disclosed, andin which like reference charactors have been ,used to designate similarparts throughout all views, numeral 10 denotes the body portion of apercolator, which ispre-ferablj formed of aluminum. In one of the wallsof the vessel a. hole 11 is cut, the marginal edges of. which are turnedback as shown at 12 in. Fig. 3 to form a continuous substantiallyU-shaped flange or guidefor the reception of a. spout 1 bit being notedthat the opposed portions of the flange are spread outwardly togive thesame a wedge-like function when the spout is applied as will presentlyappear. It will be readily apparent from Fig. 3 that the hole 11 maybeso formed that a depending tongue 13 will be formed to prevent theliquid within the percolator from coming outtoo fast.

The open back of the spout 14 is being provided with an out-turnedmarginal sub stantially U-shaped flange 14 which is reverted inwardly asshown at 14 thus forming between the outward and reverted porti n 1% anserenel a g e 14;"

on the for the reception of the edge of the outturned U-shaped spoutcarrying flange 12 of the percolater previously described.

From the foregoing it will be apparent that the flange 12 may be engagedin the groove 14 and the spout 14 moved thereon to the relation shown inFigs. 1 and 4. This having been accomplished, the next step is to soclamp the spout to the flange 12 and body of the vessel as to present asmooth and attractive joint and one which will b strong, durable andleak-proof. The above result is attained by the employment of suitabledies, the application and use of which indents the wall of the vesseladjacent the out-turned flange 12 inwardly as shown at 15 in Figs. 7 and9. This results in the lateral portion 14 of the spout 14 being locatedflush with the outer surface of the vessel. A liquid tight joint will beprovided, but in order to' make doubly sure of this, it is best to placea thin layer of litharge or similar substance within the groove 14 ofthe spout 14 and also v in the groove formed by the flange 12 and thebody of the vessel 10 preparatory to locating the spout as shown inFigs. 4 and 9. Then, upon the application of the dies to form the jointas shown in Fig. 9, the associated flanges will be securely clampedtogether and the litharge will prevent any possibility of leakage of thecontents of the vessel out through the spout joint.

In Figs. 6 and '7 it will be noted that the tongue 13 is formedconsiderably longer than in Fig. 3. In this embodiment, it is notnecessary to cut a hole 11 but merely to make a U-shaped slit in thefront of the vessel and bend marginal edges outwardly. This tongue 13 ofFig. 6 may be apertured as shown at 13 and a pair of marginal stiffeningribs 13 are preferably provided, which tend to keep the tongue rigid andin engagement with the adjacent surface of the spout 14, as clearlyshown in dotted lines in Fig. 7. I

' When the short tongue 13 is employed, it is often necessary in order,to properly strain the contents of the vessel or to keep the aroma fromescaping therefrom to pro vide a closure slide or strainer member 16,

as the case may be, which is indicated in Fig. 5 as being insertedbetween the tongue 13 and the adjacent lateral flange of the especiallydesirable where the vessel is of I aluminum since such articles are notenaneled or otherwise covered to fill in cracks and crevices which wouldoccur in other forms of joints to gather dirt or render the containerlikely to leak. The spout 14may be quickly applied and upon the application"'of stamping dies the attached portion of the spout will lie flushwith the outer surface of the vessel wall, the joint being hardlyperceptible. But one stroke of the dies is necessary to'secure theresult and the double groove construction at the site of the jointeffectually prevents leakage and gives four thicknesses of metal toassure rigidity.

In accordance with the patent statutes I have described and illustratedherein the preferred embodiment of my invention but it will bedistinctly understood that Ido not propose to limit myself strictly tothe details set forth since various changes and modifications thereofwillimmediately suggest themselves to those skilled in the art withoutdeparting from the spirit of my invention, the scope of which is definedthe following claim.

I claim:

An improved vessel of the class described including a body having aU-shaped slit provided with out turned ends and formed adjacent the topof the side wall of'said vessel, the material on the outer side of theslit being rolled outwardly throughout the length of the slit to form aflange on the exterior of the body for engagement by'a spout flange. thematerialwithin said slit forming a downwardly extending tongue integralwith the body at its upper end, said tongue beingprovided'with amultiplicity of perforations therein, said tongue further havingstiffening ribs adjacent lits sides.

In testimony whereof I aflix my signature.
